Hi fellow designers!
Not sure if this has been mentioned before, but heres a thought. As I share my Invision links to non-designers of my company, I usually like to give them some sort of an introduction screen and an ending screen. I would have to create these elements/screens and hotspots again and again, but it would be nice if there was an Invision integrated welcome for the start and a nice well done at the end of a Prototype. It would clear up any confusion where someone viewing the link may think there is more to the prototype, when they actually finished the steps intended. It would also help for times when I can't always be there to introduce or guide viewers. This way they can feel guided, they can start again or proceed to the next flow, etc. Maze has a great friendly example of how they introduce the user who is about to test a prototype. They even give a job well done with confetti when they reach the end. I think this would be fantastic to be applied for simply viewing and sharing prototypes too!
